MSP430FG4618/f2013 Experimenter's Board Windows Hyperterminal

Other Parts Discussed in Thread: MSP430FG4618

Hi there,

I am currently using the MSP430FG4618/f2013 Experimenter's Board with the MSP-FET430UIF USB Debug interface connected via the JTAG1 to use the FG4618 chip.

The code I am running is the msp430xG46x_uscia0_uart_9600.c from the TI examples. I have setup IAR to use the recommended settings for this board. I have also followed the instructions from this link (http://e2e.ti.com/support/microcontrollers/msp43016-bit_ultra-low_power_mcus/f/166/t/19613.aspx?PageIndex=1) for changes to the code required for my specific board. essentially I am looking to communicate with the board by sending a single character through my USB COM port and recieving data in return using matlab as my interface and data processing application. I have resorted to using windows hyper terminal as my interface for the time being until I can figure out why I am receiving no data back from the board. 

If I download and debug the program using IAR, run the program and then open windows hypreterminal using my settings for that port it tells me the port is being used by another program making this difficult to debug (same as when trying to use matlab). If I download and debug the program using IAR, run the program, set the option to leave target running and then exit the debugger I can then use windows hyperterminal to open a connection to the correct COM port. My issue is that I cannot type anything into the hyperterminal screen which makes me believe that there isnt actually a connection to the board at all. My settings for Windows Hyper Terminal are...

Bits per second: 9600

Data bits: 8

Parity: none

Stop bits: 1

Flow control: Hardware

 

I have also checked multiple times to ensure I am connecting to the correct port (MSP-FET430UIF - Serial Port (COM7) in device Manager)

 

Edit: I am also using the newst version of IAR kickstart 5.4

    Hi,

    I am not sure how you are trying to communicate over the JTAG port using the USCIA0.  If you see the schematics in the kit user guide, http://www.ti.com/litv/pdf/slau213a, you will notice that pins 2.4 & 2.5 lead to G2 DB9 connector. So you will need to connect to this port to see the serial echo. Also in the serial port settings, set "Flow Control" to "None".

    Regards,

    Praval

    Thanks for the clear reply.

    I was under the impression that I would simply be able to communicate through the JTAG to the computer. I see now that this is not the case

    Hi, I’m trying to use my PC to communicate with my MS430FG4618/2013 experimenter’s board via the serial port (COM1).  I’m using the code suggested in http://e2e.ti.com/support/microcontrollers/msp43016-bit_ultra-low_power_mcus/f/166/t/19613.aspx?PageIndex=1

    I’m having the same problem as some other people in this forum.  Yes, I do have a serial cable connected between the PC and the board.  The Hyperterminal setting is

    ·         Bits per second: 9600

    Data bits: 8

    Parity: none

    Stop bits: 1

    Flow control: None

     

    I’m not able to type in or see anything in the Hyperterminal.  I’m sure my COM1 is good since I’m using it for something else.  Any solution?  Thanks.

     

     

     

     

    #include  <msp430xG46x.h>

    void main(void)

    {

      volatile unsigned int i;

      WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT

      FLL_CTL0 |= XCAP14PF;                     // Configure load caps

      do

      {

      IFG1 &= ~OFIFG;                           // Clear OSCFault flag

      for (i = 0x47FF; i > 0; i--);             // Time for flag to set

      }

      while ((IFG1 & OFIFG));                   // OSCFault flag still set?

      P2SEL |= 0x030;                           // P2.5,4 = USCI_A0 RXD/TXD

      ME2 |= UTXE1 + URXE1;                     // Enable USART1 TXD/RXD

      U1CTL |= CHAR;                            // 8-bit character

      U1TCTL |= SSEL0;                          // UCLK = ACLK

      U1BR0 = 0x03;                             // 32k/9600 - 3.41

      U1BR1 = 0x00;                             //

      U1MCTL = 0x4A;                            // Modulation

      U1CTL &= ~SWRST;                          // Initialize USART state machine

      IE2 |= URXIE1;                            // Enable USART1 RX interrupt

      _BIS_SR(LPM3_bits + GIE);                 // Enter LPM3 w/ interrupt

    }

     

    #pragma vector=USART1RX_VECTOR

    __interrupt void USART1_rx (void)

    {

      while (!(IFG2 & UTXIFG1));                // USART1 TX buffer ready?

      TXBUF1 = RXBUF1;                          // RXBUF1 to TXBUF1

    }
